MECHANICAL MOVEMENT..

SPECIFICATION forming part of `Letters Patent No.. 448,511, dated March 17, 1891.

Application filed July '7. 1888. Renewed August 26, 1890. Serial No. 363.095. (No model.)

T0 ctZZ whom it may concern:

Be it known that I, 1WILLIAM C. FICH, residing at Harmonsburg, Crawfordncounty, and State of Pennsylvania, have invented a new and useful Improvement in Mechanical Movements, of which the following is a specification.

My invention has for its object the con' struction of a mechanical movement by means of which increased power may be obtained; and it consists in the peculiar arrangement and combination of parts, as will be hereinafter fully described, and pointed out in the claims, reference bein g had to the accompanying drawings, in which- Figure l is a top plan view, parts being broken away. Fig. 2 is a rear View; and Fig. 3 is a vertical longitudinal section on the line 3 3, Fig. l.

Referring to the drawings, A indicates a suitable frame, which consists of a base c, vertical standards a a a a5, and cross-tim bers a2 a2 a3.

Between the timbers a ct is mounted a cross-shaft B, which is provided with avseries of pulleys or disks C C, disposed between the standards a a', and a drive-pulley D, fixed on the outer extended end B, to which pulley is applied the drive-belt B2, as shown.

Between the standards a4 a4 and short posts o. a6 is mounted a fixed shaft E, and on this shaft are journaled to rock thereon a series of levers F, having their forward-projecting arms F extended a short distance to each side of the disks C, as shown.

Upon both faces of the disks C and near the outer rims thereof projects a stud c, upon which is mounted a friction-roller G. The

studs c and rollers G are, however, disposed at irregular intervals upon the disks, the construction of the same shown in the drawings, presenting an approximately spiral arrangement about the shaft B of the entire series of rollers G, for a purpose as will be presently p is also provided at its outer extended end with a band-pulley H3, as shown. Upon their rear ends the levers F, which extend ashort distance in rearof the shaft E, are provided with gravity-pawls J J', which are arranged to engage the ratchets Il of the shaft H.

Depending from the cross-timber a3 is a series of brackets L L, in which are journaled pulleys M M, arranged in pairs and over which pass leather straps N N, connected at their lower ends to the levers.

In the construction shown in the drawings I have illustrated four disks C, eight levers F, four pairs of pulleys M, and four straps N. By this arrangement it will be seen that each disk operates a pair of levers F, and that one end of one of the leather straps N is connected to one of the levers F, passes overone pair of pulleys M, then down, and connects to the next succeeding fourthlever. As before stated, the ends of the levers extend .a short distance within the inner edges of the disks C.

By reference to Fig. 3 it will be observed that the inner ends F of the levers are beveled at fand provided with friction-plates f. These ends are arranged to be operated upon by the rollers G upon the disks, which travel upon the beveled front edgefand` force the forward ends of the levers down, which movement causes the rear ends of the levers to rise and through the medium of the gravitypawls operate upon the ratchet-collars Il', and thereby revolve the shaft H. The peculiar arrangement of the rollers G upon the several disks serve to operate the levers alternately. Thus when the end lever F3 is being operated upon by the roller G4 and is thrust downward to its farthest extent the roller Gtt will be at its lowest point and just about ready to leave the end of the lever F3. The strap N4, which is connected to the lever F3 at one end n, passes over the first pair of pulleys M, and has its other end connected to the lever F4, and is by it, (the strap,) when the lever F3 is in its lowest position, pulled up toits highest point, and is just about ready to be operated upon by the roller G5, which is at this time in its uppermost position. The same relative positions being presented in relation to the other levers, rollers, and disks, a further description of them is deemed unnecessary. Thus by this operation it will be seen that a number of the levers will be forced IOO upward at their rear ends and cause the pawls to operate and turn the shaft II, while the remaining levers and their pawls will be on their downward movement, and thus the shaft Il will be continuously turned by the alternate operation of different sets of pawls. XVashers K are placed on the shaft between the levers to properly space the same.

Arms b' S extend downwardly from the cross-timbers d3, and are connected by a crossbar T, which is disposed above and near the inner ends of the levers to limit their upward movement.

In the upper ends of the standards di a5 is journaled the power-transmitting shaft O, having a pulley O at one end, connected by a belt O2 with the pulley Il3 upon the shaft Il, a band-pulley O3, fixed upon the shaft, and a balal'ice-wheel l), keyed or otherwise secu red to the outer end 06 thereof.

Frein the foregoing description, in connection with the drawings, the advantages of my improvement will be readily understood.

By arranging the levers in the manner described and operating them as stated a considerable amount of leverage is obtained, and thereby imparts an increased power to operate the shaft Il. This power may be increased by lengthening the levers F and placing their pivotal connection at a greater distance from the disks.

While I have shown and described disks C placed upon the shafts B, it is manifest that in large machinery wheels may be employed having the rollers attached to their rims. It is also manifest that the several constructions of the different parts may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a mechanical movement, the combination, with the shaft Il, having a series of ratchet-collars Il fixed thereon,a shaft E, arranged parallel thereto, and a series of levers joui-n aled near their rear ends upon said shaft E, provided at their rear ends with pawls adapted to alternately engage the ratchetcollars II', whereby a continuous motion is applied to the shaft II, of the drive-shaft B, provided with disks having projections adapted to alternately force the front end of said levers down, and means, substantially as described, for alternately raising the forward end of said levers, as and for the purposes described.

2. The combination, with the shaft II, provided with ratehet-collars Il', the shaft E, arranged parallel to the shaft II, and levers F, journaled upon the shaft E, their rear ends extending toward the shaft Il and provided with gravity-pawls adapted to engage the ratchcts ll', of the power-shaft B, provided with a drive-pulley D and disks C, xed thereon, said diskshavingprojections C, having friction-rollers G mounted thereon, and said disks arranged to alternately operate upon the front ends of the levers F, and lneans, substantially as shown and described, for raising the front ends of said levers, substantially as and for the purposes described.

3. Thecombination,withtheshaft II,having ratchet-collars H secured thereon, the shaft E, arranged parallel to the shaft II, and the levers F, mounted on the shaft E, having their rear ends extending toward the shaft II and provided with pawls adapted to engage the ratchets II', the forward ends of said levers connected to straps N, each of said straps connected at one end to one lever and then passed over a pair of pulleys M, attached to another one of said levers, whereby when one of said. levers shall be lowered the other will be raised, of the power-shaft B, provided with disks C, carrying projecting rollers G, arranged on the disks in a spiral about the shaft B, said projections adapted to alternately engage the front ends F of the levers F, whereby the rear ends of said levers, with the pawls, are alternately raised, thus giving a continuous motion to the shaft Il, all arranged substantially as and for the purposes described.

4. The combination, with the shaft lf and ratchet collars Il secured thereon, of the shaft E, arranged parallel to the shaft Il, levers F, journaled thereon, their rear ends extending toward the shaft II and provided with gravitypawls adapted to engage the ratchets II', and means, substantially as shown and described, for raising and lowering the forward ends of said levers F, said levers arranged to be alternately lowered and raised in series, whereby one series will be raised while the other is lowered, thereby causing a continuous revolution of the shaft Il, as and for the purposes described.

5. The combination, with the shaft Il, provided with ratchet-eollars Il, the sl1aftE,arranged parallel to the shaft Il, and the levers F, mounted on said shaft E, having their rear ends extending rearwardly toward the shaft II and provided with gravity-pawls adapted to engage the ratchets II', the forward ends of said levers connected to straps N, each of said straps N connected at one end to one leverand then passed over a pair of pulleys M, and its other end attached to another of the said levers F, whereby when one of said levers is raised the other will be lowered, the power-shaft B, having disks provided with projections adapted to alternately operate upon the beveled front ends of said levers, of the depending bars S S and cross-bar T, arranged above and near the front ends of said levers, substantially as and for the purposes specified.
